A Guide to Building Bitcoin Applications on Citrea
summary
An EVM-compatible ZK rollup that proves blocks with RISC‑Zero ZKVM and publishes data on Bitcoin so BTC is the native gas and asset. A BitVM‑inspired bridge called Clementine uses on‑chain challenge games plus ZK proofs to eject malicious signers, shifting trust from “honest majority” to at least one honest participant. Testnet runs, $17M in funding, a hackathon with Open Innovation and DeFi tracks, and a Citrea Origins program already incubating wallets, a BTC stablecoin, a native DEX, money markets and SMS offline payments.
